I have a Regency R1080 scanner. It scans good, it programs good, but when it stops on a station you can not hardly understand the audio, I have replaced the output audio IC chip LM386 and all of the capacitors around it, plus the speaker. That made no difference. It seems worse on UHF, where all you can hear is the carrier and the audio seems non existant, but on the wx channels you can hear audio, but almost so distored as unable to understand.
I would sincerly apprecte any thoughts that you may have. Thank you.... Claude WB4WHH
